The UK Smart Meter rollout promises much on the surface but delivers much less than you might expect, especially if you are interested in data analysis. The 'In Home Display' (IHD) shows pretty charts in real time & some crude historical reports but offers no way to get the raw data out. If you're lucky your energy supplier might give you the data via an API or you can get it via a trusted third party but the data granularity (30 mins) is way lower than the meter can actually report (15 secs).
